  $lang_name = $ttnames{'LANGUAGE'}{'ALT '};             # returns 'Altai'
  
  # Map iso639-2 tag to/from OT lang tag
  @isotags = $iso639{'ALT '};    # returns [ 'atv', 'alt' ]
  $lang_tag = $iso639{'atv'};    # returns 'ALT '
    
  # Read latest tags file to add to built-in definitions
  readtagsfile ("C:\\Program Files\\Microsoft VOLT\\TAGS.txt");
